Detailed Information

How it works

Jakafi may work by blocking specific enzymes (JAK1 and JAK2) involved in blood cell production and immune function. These enzymes are often overactive in conditions like myelofibrosis, contributing to abnormal cell growth. By inhibiting them, Jakafi may reduce spleen size and improve symptoms related to overproduction of blood elements.

Clinical applications

According to Drugs.com, Jakafi is approved to treat intermediate or high-risk myelofibrosis, including cases with secondary anemia. It’s also used in other blood-related conditions. Dosage is based on laboratory markers, and anemia may influence starting doses and monitoring strategies.

Safety and Effectiveness

Safety profile

Common side effects of Jakafi can include low platelet or red blood cell counts, bruising, dizziness, and infection risk. According to the official prescribing document from the Israeli Ministry of Health (MOH Israel), hematologic monitoring is essential to minimize serious risks.
